Fifty million people get infected with dengue fever every year in more than hundred countries.All conventional methods fail to prevent people from getting infected.Humans get infected with dengue when ‘Aedes aegypti’ mosquito’s carrying dengue virus bite them.

Dengue fever begins with a sudden high fever, often as high as 104 – 105 degrees Fahrenheit.

A flat, red rash may appear over most of the body 2 – 5 days after the fever starts. A second rash, which looks like the measles, appears later in the disease. Infected people may have increased skin sensitivity and are very uncomfortable.

There is no specific treatment for dengue fever. You will need fluids if there are signs of dehydration. Acetaminophen (Tylenol) is used to treat a high fever. Avoid taking aspirin.

The condition generally lasts a week or more. Although uncomfortable, dengue fever is not deadly. People with the condition should fully recover.However prevention is better than cure stands by in this case also.

T.Walker(University of Queensland) and A.Hoffman(University of Melbourne) have made the aedes aegypti mosquito completely resistant to the dengue virus infection.They introduced wolbachia bacterium.It is a common bacterium that infects insects and mosquitos into the aedes aegypti.Since the bacterium lives inside the host’s cells , it makes the mosquitos resistant to the dengue virus
